Description

光源模組及顯示裝置Light source module and display device

本創作是有關於一種光源模組，且特別是有關於一種能用於顯示裝置的光源模組以及使用此光源模組的顯示裝置。This creation relates to a light source module, and in particular to a light source module that can be used in a display device and a display device using the light source module.

液晶顯示裝置包括液晶顯示面板與背光模組。由於液晶顯示面板本身不發光，因此需要靠背光模組提供顯示光源至液晶顯示面板。因此，背光模組的主要功能就是提供高輝度以及高均勻度的顯示光源。The liquid crystal display device includes a liquid crystal display panel and a backlight module. Since the liquid crystal display panel itself does not emit light, it is necessary to rely on the backlight module to provide the display light source to the liquid crystal display panel. Therefore, the main function of the backlight module is to provide a high-brightness and high-uniformity display light source.

背光模組在傳統上可分為側入式背光模組與直下式背光模組。一般而言，直下式背光模組適於分區調光（local dimming），光源之間會以隔柵隔開。此外，為了承載光學膜片，發光區的外圍也會配置有邊框。Traditionally, backlight modules can be divided into edge-type backlight modules and direct-type backlight modules. Generally speaking, direct-lit backlight modules are suitable for local dimming, and light sources are separated by barriers. In addition, in order to carry the optical film, a frame is also arranged on the periphery of the light-emitting area.

然而，隔柵與邊框的使用會使得整體的光學亮度降低，導致背光模組的光利用率變差。並且，隔柵會額外增加背光模組的重量，使得液晶顯示裝置整體而言無法朝向輕薄化的方向發展。However, the use of barriers and frames will reduce the overall optical brightness, resulting in poor light utilization efficiency of the backlight module. In addition, the grille will additionally increase the weight of the backlight module, so that the liquid crystal display device as a whole cannot develop in the direction of lightness and thinness.

有關本創作之前述及其他技術內容、特點與功效，在以下配合參考圖式之一較佳實施例的詳細說明中，將可清楚的呈現。以下實施例中所提到的方向用語，例如：上、下、左、右、前或後等，僅是參考附加圖式的方向。因此，使用的方向用語是用來說明並非用來限制本創作。The aforementioned and other technical content, features and effects of this creation will be clearly presented in the following detailed description of a preferred embodiment with reference to the drawings. The directional terms mentioned in the following embodiments, for example: up, down, left, right, front or back, etc., are only directions for referring to the attached drawings. Therefore, the directional terms used are used to illustrate and not to limit this creation.

圖1是本創作一實施例的光源模組的剖面示意圖。圖2是本創作一實施例的光源模組的局部區域俯視示意圖。請參考圖1及圖2，本實施例的光源模組10包括基板100、反射片200、多個發光元件300、黏合層400以及膠框500。反射片200配置於基板100上，並具有側壁210、凸起部220及多個開孔230。多個發光元件300配置於基板100上，這些發光元件300分別對應穿設於這些開孔230。黏合層400例如是配置於基板100及反射片200之間。膠框500配置於基板100上，並圍繞反射片200以及多個發光元件300。FIG. 1 is a schematic cross-sectional view of a light source module according to an embodiment of the invention. FIG. 2 is a schematic top view of a partial area of a light source module according to an embodiment of the invention. Please refer to FIGS. 1 and 2, the light source module 10 of this embodiment includes a substrate 100, a reflective sheet 200, a plurality of light-emitting elements 300, an adhesive layer 400 and a plastic frame 500. The reflective sheet 200 is disposed on the substrate 100 and has a side wall 210, a protrusion 220 and a plurality of openings 230. A plurality of light-emitting elements 300 are disposed on the substrate 100, and the light-emitting elements 300 are respectively penetrated through the openings 230. The adhesive layer 400 is, for example, disposed between the substrate 100 and the reflective sheet 200. The plastic frame 500 is disposed on the substrate 100 and surrounds the reflective sheet 200 and the plurality of light-emitting elements 300.

反射片200的凸起部220朝遠離基板100的方向凸起，且於俯視方向上呈現具有多個網眼的網狀結構（如圖2所示），以定義出多個調光區域A。在本實施例中，多個調光區域A例如呈陣列排列，但不以此為限。多個開孔230分別對應於這些調光區域A，意即，每一調光區域A內皆具有一個發光元件300。相鄰的任兩發光元件300之間被反射片200的凸起部220所隔開。此外，凸起部220於基板100上的高度會大於發光元件300於基板100上的高度。藉此，可以降低每一調光區域A內的發光元件300所發出的光線L漏光到另一調光區域A的機率，以避免影響亮度對比及調光效果。圖1及圖2中的多個開孔230及多個調光區域A的數量僅為示意，並不以此為限。The protruding portion 220 of the reflective sheet 200 protrudes in a direction away from the substrate 100 and presents a network structure with multiple meshes (as shown in FIG. 2) in the top view direction to define a plurality of dimming regions A. In this embodiment, the plurality of dimming areas A are arranged in an array, for example, but it is not limited to this. A plurality of openings 230 respectively correspond to these dimming areas A, which means that each dimming area A has a light-emitting element 300. Any two adjacent light-emitting elements 300 are separated by the protrusion 220 of the reflective sheet 200. In addition, the height of the protrusion 220 on the substrate 100 is greater than the height of the light emitting element 300 on the substrate 100. Thereby, the probability of the light L emitted by the light-emitting element 300 in each dimming area A from leaking to another dimming area A can be reduced, so as to avoid affecting the brightness contrast and the dimming effect. The number of the plurality of openings 230 and the plurality of dimming regions A in FIG. 1 and FIG. 2 is only for illustration, and not limited thereto.

另一方面，反射片200的側壁210例如是配置於膠框500上。具體而言，側壁210為反射片200接觸於膠框500的延伸部分。膠框500具有頂面510、底面520、外側面530及內側面540。頂面510與底面520相對，外側面530與內側面540相對。在本實施例中，反射片200的側壁210例如配置於內側面540及頂面510上，但不以此為限。在另一實施例中，反射片200的側壁210也可以僅配置於內側面540。On the other hand, the sidewall 210 of the reflective sheet 200 is, for example, disposed on the plastic frame 500. Specifically, the side wall 210 is an extension part of the reflective sheet 200 in contact with the plastic frame 500. The plastic frame 500 has a top surface 510, a bottom surface 520, an outer side surface 530, and an inner side surface 540. The top surface 510 is opposite to the bottom surface 520, and the outer side surface 530 is opposite to the inner side surface 540. In this embodiment, the sidewall 210 of the reflective sheet 200 is, for example, disposed on the inner side surface 540 and the top surface 510, but it is not limited to this. In another embodiment, the sidewall 210 of the reflective sheet 200 may also be only disposed on the inner side surface 540.

在本實施例中，反射片200例如為一體成型，但不以此為限。具體而言，反射片200是將平坦的反射片經真空吸塑（Vacuum forming）製程後形成凸起部220。本創作並不特別限制凸起部的形狀，可以依據設計需求調整，並且，反射片200例如也可以是由多片反射片拼接而成。In this embodiment, the reflective sheet 200 is, for example, integrally formed, but it is not limited to this. Specifically, the reflective sheet 200 is formed by subjecting a flat reflective sheet to a vacuum forming process to form the protrusions 220. The present invention does not particularly limit the shape of the protrusions, and can be adjusted according to design requirements. In addition, the reflective sheet 200 may also be formed by splicing multiple reflective sheets, for example.

基板100例如是印刷電路板，可為硬板或軟板，用來承載反射片200、發光元件300及膠框500，並透過基板100來驅使發光元件300發光。The substrate 100 is, for example, a printed circuit board, which can be a rigid board or a flexible board, and is used to carry the reflective sheet 200, the light-emitting element 300, and the plastic frame 500, and drives the light-emitting element 300 to emit light through the substrate 100.

發光元件300可為發光二極體，但也可以是其他種類的發光元件。此外，發光元件300也可以是直接自一片晶圓切割出且未經封裝的發光晶片，例如為發光二極體晶片。舉例而言，所述的發光二極體晶片例如是主波長發出藍光的晶粒級氮化物發光二極體晶片，但不以此為限。圖1的發光元件300的數量是以3個為例，但不以此為限。此外，發光元件300在基板100上呈陣列排列，如圖2所示。應注意的是，圖2旨在呈現凸起部220的形狀以及多個調光區域A與多個發光元件300的排列方式，對於多個調光區域A與多個發光元件300的形狀與數量僅為示意，本創作並不特別限制。The light-emitting element 300 may be a light-emitting diode, but may also be other types of light-emitting elements. In addition, the light-emitting element 300 may also be a light-emitting chip that is cut directly from a wafer and is not packaged, such as a light-emitting diode chip. For example, the light-emitting diode chip is, for example, a grain-level nitride light-emitting diode chip that emits blue light at a dominant wavelength, but it is not limited to this. The number of light-emitting elements 300 in FIG. 1 is three as an example, but it is not limited thereto. In addition, the light-emitting elements 300 are arranged in an array on the substrate 100, as shown in FIG. 2. It should be noted that FIG. 2 is intended to present the shape of the protrusion 220 and the arrangement of the plurality of dimming areas A and the plurality of light-emitting elements 300. For the shape and number of the plurality of dimming areas A and the plurality of light-emitting elements 300 For illustration only, this creation is not particularly limited.

黏合層400的作用在於將反射片200固定於基板100上，因此只要能達到此效果，本創作並不特別限制黏合層400的材質。舉例而言，可以是黏合劑或黏合膠帶，也可以選用具有導熱效果的導熱膠等。在本實施例中，黏合層400例如還配置於基板100及膠框500之間，但不以此為限。習知常見的膠框固定方式為以螺絲鎖固或卡勾固定，然而螺絲鎖固需要花費較長組裝時間，卡勾則容易有變形問題。本實施例的光源模組10直接以黏合層400將膠框500黏合於基板100上，在組裝程序上較為簡單且可以節省時間成本。The role of the adhesive layer 400 is to fix the reflective sheet 200 on the substrate 100, so as long as this effect can be achieved, the present invention does not particularly limit the material of the adhesive layer 400. For example, it can be an adhesive or adhesive tape, or a thermally conductive adhesive with thermal conductivity. In this embodiment, the adhesive layer 400 is also disposed between the substrate 100 and the plastic frame 500, for example, but it is not limited to this. The conventional fixing method of the plastic frame is fixed with screws or hooks. However, the screw locking requires a long assembly time, and the hooks are prone to deformation problems. In the light source module 10 of this embodiment, the plastic frame 500 is directly bonded to the substrate 100 by the adhesive layer 400, which is relatively simple in the assembly procedure and can save time and cost.

本實施例的光源模組10例如還包括光學膜片組600，配置於膠框500上並由膠框500所承載。光學膜片組600包括至少一光學膜。光學膜片組600的至少一光學膜例如是偏光增亮膜、擴散膜、稜鏡片或複合式稜鏡片等，但不以此為限。本創作並不限制至少一光學膜的數量，其可為一片或多片，在本實施例中是以三片光學膜610、620、630為例，且依序堆疊於膠框500上。此外，依據光學膜功能的不同，光學膜610、620、630也可分別選用不同的種類。應注意的是，圖2中為清楚顯示反射片200的凸起部220的形狀，因此並未繪示光學膜片組600。The light source module 10 of this embodiment, for example, further includes an optical film set 600, which is disposed on and carried by the plastic frame 500. The optical film set 600 includes at least one optical film. The at least one optical film of the optical film set 600 is, for example, a polarizing brightness enhancement film, a diffusion film, a thin film or a composite film, etc., but it is not limited thereto. The present invention does not limit the number of at least one optical film, which can be one or more sheets. In this embodiment, three optical films 610, 620, and 630 are taken as an example, and they are stacked on the plastic frame 500 in sequence. In addition, depending on the function of the optical film, the optical films 610, 620, and 630 may also be of different types. It should be noted that the shape of the protrusion 220 of the reflective sheet 200 is clearly shown in FIG. 2, so the optical film set 600 is not shown.

本實施例的光源模組10中，反射片200具有呈現網狀的凸起部220，並定義出多個調光區域A，多個發光元件300分別對應配置於多個調光區域A中。因此，凸起部220可以取代習知直下式光源模組中的隔柵，在達到區域調光效果的同時，還能減輕光源模組10的重量。此外，反射片200的側壁210還配置於膠框500上，由於反射片200本身的反射光線L的效果，使得傳遞至習知直下式光源模組中隔柵或邊框的光線，在本實施例的光源模組10中可以被反射片200反射，進而提升光利用率。In the light source module 10 of this embodiment, the reflective sheet 200 has a mesh-shaped protrusion 220 and defines a plurality of dimming areas A, and the plurality of light-emitting elements 300 are respectively arranged in the plurality of dimming areas A. Therefore, the raised portion 220 can replace the barriers in the conventional direct-type light source module, and can reduce the weight of the light source module 10 while achieving the regional dimming effect. In addition, the side wall 210 of the reflective sheet 200 is also disposed on the plastic frame 500. Due to the effect of the reflective sheet 200 itself reflecting light L, the light transmitted to the grille or frame of the conventional direct-lit light source module, in this embodiment The light source module 10 can be reflected by the reflective sheet 200, thereby improving the light utilization efficiency.

圖3是本創作另一實施例的光源模組的剖面示意圖。請參考圖3，本實施例的光源模組10a與上述的光源模組10結構及優點相似，以下僅針對其結構的主要差異處進行說明。本實施例的光源模組10a中，反射片200a的側壁210a例如具有多個貫孔211，並且膠框500a例如為透明導光膠框。原則上，這些貫孔211的孔徑D1小於多個開孔230的孔徑D2，但不以此為限。多個貫孔211的用途在於，使得傳遞至光源模組10a邊緣的光線L能穿過這些貫孔211後入射膠框500a。本實施例的光源模組10a例如還包括反射層700，配置於膠框500a的外側面530及底面520。當光線L入射膠框500a後，可以被反射層700反射後再經由位於膠框500a的頂面510以及內側面540的反射片200a的側壁210a的這些貫孔211出射。本創作並不特別限制貫孔211的數量、尺寸及分布密度等，可以依據設計需求調整。藉由上述設計，本實施例的光源模組10a可以減少不發光的邊框區域，達到邊框薄型化，近似於無邊框的效果。FIG. 3 is a schematic cross-sectional view of a light source module according to another embodiment of the invention. Please refer to FIG. 3, the light source module 10a of this embodiment is similar in structure and advantages to the light source module 10 described above, and only the main differences of the structure are described below. In the light source module 10a of this embodiment, the sidewall 210a of the reflective sheet 200a has a plurality of through holes 211, and the plastic frame 500a is, for example, a transparent light-guiding plastic frame. In principle, the diameter D1 of the through holes 211 is smaller than the diameter D2 of the openings 230, but it is not limited to this. The purpose of the multiple through holes 211 is to enable the light L transmitted to the edge of the light source module 10a to pass through the through holes 211 and enter the plastic frame 500a. The light source module 10a of this embodiment, for example, further includes a reflective layer 700, which is disposed on the outer side surface 530 and the bottom surface 520 of the plastic frame 500a. When the light L enters the plastic frame 500a, it can be reflected by the reflective layer 700 and then exit through the through holes 211 of the sidewall 210a of the reflective sheet 200a on the top surface 510 and the inner side 540 of the plastic frame 500a. This creation does not particularly limit the number, size and distribution density of the through holes 211, and can be adjusted according to design requirements. With the above-mentioned design, the light source module 10a of this embodiment can reduce the non-luminous frame area, and achieve a thinner frame, which is similar to the effect of no frame.

在本實施例中，配置於頂面510的反射片200a的側壁210a例如具有彎折部212，適於固定光學膜片組600。具體而言，彎折部212是先朝遠離基板100的方向延伸，再朝向面對多個發光元件300的方向彎折，亦即彎折部212朝遠離基板100的方向延伸後，再沿著實質上平行於基板100且朝向膠框500a所圍繞的區域內的方向彎折延伸，使得彎折部212與位於膠框500a的頂面510的部分反射片200a共同形成類似凹槽狀的結構，使得光學膜片組600的邊緣由位於膠框500a的頂面510的部分反射片200a所承載且位於彎折部212與位於膠框500a的頂面510的部分反射片200a共同形成類似凹槽狀的結構內。本實施例的彎折部212僅為示例，並非限制本創作固定光學膜片組600的方式。彎折部212例如也可以適用於上述的光源模組10。此外，多個貫孔211也配置於彎折部212，例如彎折部212中平行於基板100且朝向膠框500a所圍繞的區域內的方向的部分具有多個貫孔211，因此從膠框500a出射的光線L仍能通過光學膜片組600後，再經由前述彎折部212的多個貫孔211出射，除了可減少不發光的邊框區域，達到無邊框的效果，且可降低光線L直接出射的機會，達到減少邊緣亮線的現象。In this embodiment, the side wall 210 a of the reflective sheet 200 a disposed on the top surface 510 has, for example, a bent portion 212, which is suitable for fixing the optical film set 600. Specifically, the bent portion 212 first extends in a direction away from the substrate 100, and then is bent in a direction facing the plurality of light-emitting elements 300, that is, the bent portion 212 extends in a direction away from the substrate 100, and then along It is substantially parallel to the substrate 100 and bends and extends toward the direction in the area surrounded by the plastic frame 500a, so that the bent portion 212 and the partial reflection sheet 200a located on the top surface 510 of the plastic frame 500a together form a groove-like structure. The edge of the optical film set 600 is carried by the partially reflective sheet 200a located on the top surface 510 of the plastic frame 500a, and the partially reflective sheet 200a located at the bent portion 212 and located on the top surface 510 of the plastic frame 500a together form a groove-like shape. Within the structure. The bending portion 212 in this embodiment is only an example, and does not limit the method of fixing the optical film set 600 in the present invention. The bending part 212 can also be applied to the above-mentioned light source module 10, for example. In addition, a plurality of through holes 211 are also arranged in the bending portion 212. For example, the portion of the bending portion 212 that is parallel to the substrate 100 and facing the direction in the area surrounded by the plastic frame 500a has multiple through holes 211, so the plastic frame The light L emitted from 500a can still pass through the optical film set 600, and then exit through the plurality of through holes 211 of the aforementioned bending part 212. In addition to reducing the non-luminous frame area, the effect of frameless is achieved, and the light L can be reduced. The chance of direct emission can reduce the phenomenon of bright lines on the edge.

The light-shielding layer 800 is, for example, a light-shielding tape or a light-shielding ink, but not limited thereto. The light-shielding layer 800 of this embodiment, for example, also extends to the bent portion 212, which means that the light-shielding layer 800 is disposed on the side of the light source module 10a to absorb light to avoid light leakage. When the portion of the bent portion 212 extending in the direction away from the substrate 100 does not have the through hole 211, and the outer surface 530 of the plastic frame 500a is provided with the reflective layer 700, the light shielding layer 800 does not need to be provided.
